Fog may be intermittent in some places, but I live on the west coast, right by the ocean and with a steady west-to-east wind, so there is no day without fog for here.
Other places that are not close to a large body of water will still have a change of temperature in the morning, which will cause condensation - or dew. Dew can be collected for water as well. A person can collect more than one needs for the whole year this way - as long as the water is stored - even if one or two seasons happens to be rather dry.
@Silvia Parker:
You'll need to buy a roll of plastic screening. It needs to be quite large, because you'll be collecting dew drops or fog. You'll also need to get plastic gutter to collect the water. Lastly, you'll need a container to collect the water from the gutter.
You'll also have to make a frame of some type for the screen (PVC piping is a good way). The screen will over-lap, by running from one end of the frame, on one side of it, back to the other end of the frame, but on the other side. This will double the collection area.
You'l have to be conscientious to get up early every morning and shake the water off of the screen so that it all goes in to the gutter, and into your storage container.
Check out the links below to see what I'm referring to. There may not be a Home Depot where you live, but I'm sure that you'll be able to find stores with a similar product.

FOG IS A very intermittent thing. you might want use another kind of water collector.
I've learned you can get water through fog collecting, however I've found its easier through looking around using a "Fog Fence", would anyone know how I could make, or where I could find one?
